LOS ANGELES -- Country pop diva Shania Twain is separating from her husband of 14 years, music producer Robert Lange, it was reported on Thursday.

A spokesman for the 42-year-old Canadian singer -- whose 1997 record "Come on Over" is the highest selling album of all-time by a female musician -- confirmed the split to People magazine.

"Shania Twain and her husband, music producer Robert 'Mutt' Lange, are separating after 14 years of marriage," spokesman Jason Owen told People. "This is a private matter and there will be no further comment at this time."

Twain and Lange, 59, married in 1993, six months after meeting. The couple, with homes in New Zealand and Switzerland, have a six-year-old son.

According to the Recording Industry Association of America, Twain is the only female artist to have three albums with sales of 10 million copies or more.
